Technical Field

[0001] The utility model relates to the technical field of hemiplegia auxiliary tools, in particular to a good limb positioning device capable of assisting joint activities. Background Art

[0002] Hemiplegia refers to movement disorders caused by impaired muscle function on one side of the body due to stroke, cerebrovascular accident, brain injury and other neurological diseases. Hemiplegia usually manifests as muscle weakness, stiffness or paralysis on one side of the body, which may lead to difficulty walking, decreased limb coordination and difficulty in daily activities.

[0003] Hemiplegic patients need to have their limbs positioned properly when lying in bed. Currently, pillows are used to position the hemiplegic limbs due to artificial factors. During the positioning, the pillows may lose support and slip, causing the posture to change. In addition, it is inconvenient to move the joints during the positioning. The hemiplegic limbs may also easily cause blood circulation problems and muscle spasms.
